Abstract

We undertake the study of the charged Higgs bosons predicted by the model with gauge symmetry SU(3)cSU(3)LU(1)XSU(3)_c \otimes SU(3)_L \otimes U(1)_X. By considering Yukawa mixing couplings between small (\sim GeV) and large (\sim TeV) scales, we show that the hypercharge-one H1±H_1^{\pm} and hypercharge-two H2±H_2^{\pm} Higgs bosons predicted by the model, can be simultaneously produced in pppp collisions at different production rates. At low energy, the H1±H_1^{\pm} bosons exhibit the same properties as the charged Higgs bosons from a two Higgs doublet model (2HDM), while H2±H_2^{\pm} are additional like-charged Higgs bosons from the underlying 3-3-1 model. Thus, the identification of multiple like-charged Higgs boson resonances may test the compatibility of theoretical models with experimental data. We study H1,2±H_{1,2}^{\pm} pair and associated tbH1,2±tbH_{1,2}^{\pm} productions at CERN LHC collider. In particular, we obtain that pair production can be as large as the single production in gluon-gluon collisions due to the interchange of a heavy neutral ZZ' gauge boson predicted by the model. By considering decays to leptons H1,2±τντH_{1,2}^{\pm} \rightarrow \tau \nu_{\tau}, we obtain scenarios where small peaks of H2±H_{2}^{\pm}-boson events in transverse mass distributions can be identified over the H1±H_{1}^{\pm} background.
